Abstract：Objective To explore the changes and significance of physiological indexes of recruits in intensive training. Method One hundred and twenty-six recruits in mobile forces were selected as research targets. According to the training program, they concentrated on physical training for 2 months and carried out follow-up regular inspection. Six test time points are the beginning of the training, 3 days of training, 1 week, 2 weeks, 1 month and 2 months of training; After getting up, pulse, blood pressure, height and weight were measured; Fasting venous blood was drawn for blood routine to examine C-reactive protein (CRP), myocardial zymogram, myocardial infarction, liver function, renal function, Brain Natriuretic Peptide (BNP), echocardiography. Blood oxygen and pulse were immediately measured after 1km running. Results There was no significant change in the basic physiological indicators of the recruits after the army recruits training. The maximum heart rate increased, the mean heart rate decreased, and the performance of one-kilometer running improved. After the training, the values of cardiac troponin(cTnT) and MB isoenzyme of creatine kinase(CK-MB) in blood serum increased within physiological range, Aspartate aminotransferase(AST), creatine kinase(CK), Lactate dehydrogenase(LDH) and Myoglobin(MYO) significantly increased and were much higher than the physiological values, and the physiological level of BNP recovered after mild elevation, but there was no change in CRP. Ultrasonic cardiogram showed that there was no significant change in EF value. The left ventricular stroke output significantly increased, and the interventricular septal thickness slightly decreased but remained at a range of physiological condition. The cardiopulmonary function was significantly improved after recruit training and still met the standards. Conclusion Utrasonic cardiogram and myocardial enzymology detection system may assess the myocardial injury and timely screen out high-risk cases prone to cardiovascular events in the recruit training.
